Origin of microporosity of ammonium dodecatungstophosphate unveiled by single crystal structure analysis
The single crystals of ammonium dodecatungstophosphate were successfully synthesized and the structure was analyzed. The intrinsic crystal structure (cubic, Pn (3) over barm) had no cavity. It follows that the microporosity observed for the powdery sample originated from narrow spaces surrounded by the fine nanocrystallites.
